Essential 3-1/4 X 4-1/2 X 9/16 Obround Blue Max Handhole Gaskets - 6 Pack Series [PkosR5GD]

Blue Max boiler gaskets are made from a special formula glass/elastomer-impregnated tacky cloth.

The gaskets have their sizes clearly marked for easy installation. These super-strong gaskets resist splitting due to over-tightening flange surfaces.

Key Benefits:

Zero Leakage Under Pressure: Even the slightest leakage is too much, as it increases maintenance and reduces boiler life. Tests by major boiler manufacturers confirm that Blue-Max gaskets seal- with zero leakage-on steam to 450 psi and on cold-water hydro tests up to 1500 psi and Blue-Max gaskets withstand working temperatures up to 500 degrees Fahrenheit. Rubber gaskets simply can’t withstand that kind of pressure and heat.

Easily Removed: Removal is easy and requires no scraping, chiseling or grinding. This is important in reducing the maintenance costs and down time. Sizes Clearly Marked : Each Blue-Max gasket is permanently marked with its size, so you’ll know immediately you have the appropriate one.

Easy Problem Free Installation: Blue-Max gaskets offer installation advantages over other types. Because of the materials construction and strength, there is no danger of over tightening the gasket and cutting it in half. A Blue-Max gasket naturally lays flat on the flange and requires no special installation tools, procedures or training. Simply install the gasket and crank it down.

Maximum Sealing on Rough Surfaces: Rough and pitted surfaces on old or poorly maintained flanges pose no problem for a Blue-Max gasket.The material is resilient enough to conform perfectly to surface topography and maintain the tightest possible seal.

Chemical Resistant: The proprietary Teflon wrap is resistant to the chemicals used in treating boiler water, so gaskets will last longer.

Extended Shelf Life: A Blue-Max Gasket won’t dry out or lose its strength while in sits on the shelf.
